A He-jet recoil tape-transport and X-γ(t) coincidence measurement system and new γ-rays from(EC+ β ̄+)decay of ̄(153)Er
【摘要】 介绍了He—jet带传输及X—Υ(t)符合测量装置分离鉴别重缺中于远离核的原理、速度和效率;离线测试了其最佳工作条件;利用该装置在线测量了195,196Bi、152,154Er和153Er的(EC+β+)衰变。6条新Υ射线被确定属于153Er。
【Abstract】 A He-jet recoil tape-transport and X-Υ(t)coincidence system for separating and identifying the heavy neutyon-deficient nuclei far from the stability is described including its fundamentals, speed and efficiency.Its optimal working condition has been tested off-line.The Υ-rays from 195,196Bi and 152,153,154Er(EC+β+)decay have been measured on-line by using the system. Six new Υ-rays have been assigned to 153Er.
